Abstract

The absorber and distributor element (9) for liquids in absorbent articles (1) such as nappies, sanitary towels etc. comprises a fleece layer in which microfibers are mixed with staple fibers such that their proportion continuously increases with the distance from the top surface (10) of the layer. As a result the porosity of the layer continuously diminishes with the distance from its top layer.
